All right, I'm sad now. Microsoft has removed the fullscreen console feature from Win7, which is what I'm running. Now I'm looking into things like OpenGL or SDL to see if I can emulate the console, and make it fullscreen (and I mean FULLSCREEN no window or border or anything). Is it possible to emulate the console fullscreen (like DOS) in OpenGL or something similar?

I see the tag of mingw, so probably you don't like me to propose Cygwin. With cygwin you can do Alt+shift+Enter to get full screen. And with cygwin you can also run DOS script. Since I only used it at XP before, I am not very sure about that it works in 7.
